ENGINE-STARTER FOR AUTOMOBILES.

To all whom it may concern:

Be it known that I, CARL LYNNOGK, a citizen of the United States, residing in the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Engine-Starters for Automobiles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification;

My invention relates to improvements in means for starting internal combustion en-' gines of automobiles, my object being to provide a starting device adapted to be operatedby the chauffeur without. leaving his position in the machine.

My further object is to provide a device of this character which shall be easily actuated, and which shall efficiently perform the engine-starting function, and which, after the starting function has been performed, will automatically detach itself from the engine shaft.

In carrying out my improvement, I em ploy a clutch pulley located directly in front f the free extremity of the engine shaft and so arranged that, whenthe' said pulley is actuated, clutch members will be arranged to interlock with the adjacent extremity of the engine shaft for the purpose of rotating the latter to start the engine. For this purpose, a cable is connected with the said pulley and leads to one member of a double eone shaped pulley, having spirally arranged grooves. A cable connected with the opposite member of the last-named pulley leads to a power earriagewith which a flexiblc device, to be directly actuated by the chauffeur, is attached. The double coneshaped pulley, as well as the power carriage, is constructed to give the necessary advantage whereby only a comparatively small amount of power is required for the starting of the engine.

Having briefly outlined my improved construction, I will proceed to describe the same in detail, reference beingniade to the accompanying drawing, in which is illustrated an embodiment thereof.

In this drawing: Figure 1 is atop plan view of an automobile equipped with my im- Specification of Letters Patent.

The same reference characters indicate the same parts in all. the views.

Let the numeral 5 designate the framework of an automodile carrying an engine 6, having a shaft 7, whose forward extremity is equipped with pins 8. Journaled on the framework of the machine, directly in front of the engine shaft and having its axis in alinement with the axis of the shaft, is a clutch pulley 9. Vithin this pulley is located a spring 10, one extremity of which is connected with a spindle 12, as shown at 13,

while the opposite extremity is connected,

as shown at 15, with the body 14 of the pulley. The spindle passes through a journal box 16 and is secured therein in any suitable manner, a by set bolts 17 to prevent rotation during the operation of my improved starting mechanism. If, however, it is desired to start the engine by hand, the set bolts may be loosened and a crank applied to the protruding extremity 18 of the spindle, which is-polygonal in cross section to receive a crank. socket.

Mounted within the pulley 9, which is cored out and recessed for the purpose, is a disk 19 in which dogs 20 are journaled, each dog having a journal 21 engaging a recess 22 formed in the disk 1.). One extremity of the spindle has an arm 23, adapted to project into a recess 24 formed in the body of the pulley adjacent the periphery of the disk 19, the said arm extending below a shoulder 25, formed on the pulley at the bottom of a recess 26, into which the journal extremity of the arm'23 extends during the starting movement of the pulley for the purpose of throwing the other arm 27 of the dog outwardly to engage a in 28 formed on the engine shaft. The disc 19 is also recessed, as shown at 29, to receive the arm 27 of the dog, which extends at right angles to the arm 23. As illustrated in the drawing, there are four of these dogs 20, and, as the pulley 9 is given a partial rotation, the shoulder 26 acts upon the arm 23 of each dog to impart a partial rotation to the dog on its journal 21, said rotary action being sufiicient to throw the arm 27 outwardly through a slot 30 formed in a face plate 31 secured to the disk 19 and closing all of the recesses of the disk, except those in which the arms 27 are located, these recesses 29 registering with the slots 30 of the face plate. The disk 19 is connected to the spindle 12 by means of a screw 32, whose head is countersunk in a. recess 33 formed in the center of the disk, the shank of the screw passing through an unthreaded perforation in the disk registering with a threaded opening 34 formed in the inner extremity of the spmdle. By vir- 'tue of this screw, the disk 19 is connected with the spindle, but not made fast thereto. The friction, however, between the disk and spindle and the connecting screw will be sufficient to allow the pulley body to move independently of the disk 19 until the shoulders 25 of the pulley have acted on the arms 23 of the dogs -20 to throw the arms 27 of the dogs, which normally occupy the recesses 29 in the disk, outwardly through the slots 30 in the face plate 31. The face plate 31 is secured to the disk by screws 35. As soon as the independent movement of the pulley 9 has been suliicient to throw the arms 27 of the dogs outwardly, causing the said arms to interlock with the pins 28, with which the engine shaft is equipped, the disk 19 will move with the pulley 9 sufficiently to start the engine, and, during this operation, the spring 10 will be placed under tension. As soon as the engine is started and the power on the pulley for actuating the latter has ceased to act, the recoil of the spring 10 will reverse the action of the pulley, and the wall 3901 the recess 24 will act on the arm 23 to return the dog to its normal position, whereby the arm 27 is caused to reenter its recess 29, after which the pulley and disk 19 will move together until the actuating cable 37 is rewound upon the pulley.

As illustrated in the drawing, the-cable 37 passes from the pulley 9 to a cone pulley member to which it is secured at one extremity, as shown at 39. This pulley member spirally grooved and the connection 39 is made at the base or largest part of the pulley member, and, as the cable 37 is actuated, it follows the spiral groove 40 of the pulley member 38, the circumferential length of the groove diminishing toward the small 'end of the pulley member. A second cable 41 is connected with a cone pulley member 42, as shown at 43, connection also being made at the base or largest diameter of the cone pulley member, the cable being normally wound upon the member'42 from its point of connection to its small extremity.

The two cone pulley members 38 and 42 are connected by a spiral spring 44 located within a recess-l5 formed in the two pulley members. One extremity of this spring is connected with the member 38, as shown at -:l-(l. while the other extremity connected with the member 42, as shown at 47. The strength of the spring 44 is such that, under normal conditions, the two pulley members 33 and 42 are virtually. an integral device. In the event, however, that the engine should kick, or reverse, under the influence of a premature explosion, the pulley member 38, which, during the starting'operation, is connected with the engine shaft through the medium of the cable 37 and the pulley 9 and its connections, would yield sullicicntly, by virtue of the spring connection between the two cone pulley members, to prevent injury to the mechanism.

The cable 41 passes from the cone pulley member 42 to a drum 48, being secured thereto, as shown at 49. This drum is formed integral with a gear 50 and two relatively small drums 51, the entire structure being ournaled on a shaft 52, the latter having its extremities mounted in parallel frame members 53, suitably spaced and carried by sleeves 54 slidably mounted on rods 55, whose extremities are secured to end frame bars 56 and 57, mounted on the framework of the machine. The gear 50 meshes with a smallergear 58 fast on a drum 59, the gear anddrum being ournaled on a shaft 60, whose extremities are also mounted in the parallelframe members 53., To each of the small drums51 is secured, as shown at 61, one extremity of a cable62, the opposite extremities of the said cables being made fast to the end bar 56, as shown at 64. Mounted on the rods between the slidable sleeves 54 and the end bar 56 are spiral springs 65. A flexible operating member 66 is connected with the drum 59 at one extremity, its opposite extremity extending upwardly and terminating in a hand piece 67 within reach of the chauffeur, the said flexible device passing through an opening 68 formed in the footboard 69, the hand piece 67 forn'iing astop to prevent the flexible operating member (36 from moving sary to have gears of varying diameter in connection with-the drum 4:8, in order to produce sufiiclent force to start theengine and at the same time place the springs under tension. Furthermore, the movement which places these springs 65 under tension also gives an addedpull to the cable 41 and when the tension of the said springs is released, the operating stra 66 is rewound and the carriage returne to its starting position by the expanding of the springs.

The mechanism just described and slidably mounted upon the bars 55 is herein referred to in its entirety as a power carriage and will be so designated in the claims.

Assuming now that the structure is in stalled upon an automobile, as indicated in Fig. 1 of the drawing, if it is desired to start the engine, the chauifeur'will grasp the hand piece 67 and pull forwardly on the flexible device 66, which will cause the drum 59 and the gear 58 to rotate on the shaft 60. The rotary action of the gear 58,

meshing with the gear 50, imparts a corresponding movement to the latter, and in such a direction as to wind up the cable 41 on the drum 18 and wind the cable 62 on the small drum 51. During this operation, the sleeves 54 of the power carriage are caused to move rearwardly, compressing the spring 65, both the sliding movement of the carriage and the rotary action of the drum 48 serving to pull on the cable 41 and the latteracting on the double cone pulley to rotate the latter by unwinding the cable 41 from the cone pulley member 42 and winding up the cable 37 on the cone pulley mem ber 38, whereby the clutch pulley 9 is rotated to throw the arms 27 of the dogs 20 out of the disk 19 and through the slots 30 of the face plate 31 into the path of the pins 2-8 carried by theengine shaft, whereby the latter is rotated sufliciently for starting purposes. As soon as the starting operation is complete, and the power acting on the flexible device 66 ceases to act, the recoil of the spring 10 will reverse the action of the pulley 9 and return the dogs to their normal position, within the disk 19, the pulley and disk being returned to their normal position and the cable 37 being wound thereon ready for the next starting operation.
